Please re-read the following:
I never suggested the interactable was Deathstroke's primary zoning technique. I suggested one possible solution could be baiting out the interactable, leaving it inoperative, then dash blocking past the zoning. By baiting it you might get hit by it, sure, but then it is inactive and you can rush in. Simply, if he uses it once, you have a window where you don't need to worry about it.
Even if this solution doesn't work, that doesn't mean that Deathstroke is invincible in this stage. Nightwing simply needs to meter burn his staff's ground spark to get in. Other characters have similar tools.
Every stage has possible advantages and disadvantages for each character. A match up might swing in your favor on one stage, but not another. This doesn't mean that the stages are unbalanced or unfair for tournament play, it simply adds another dimension to the game. If it is that much of an issue for you, pick a character (power or gadget, depending on your playstyle) that benefits from the placement of interactables on the stage, and learn how each stage affects your matchups.
Drawing from personal experience, I use Nightwing. In some character matchups I'm better in Staff stance, but on the level with the robot flyers overhead (can't remember which one), I'm at a horrible disadvantage in this stance. I need to switch to escrima stance, putting me at a disadvantage against my opponent, just so I can get the advantage of using interactables. Should I petition for this stage to be banned, or additional rules be created so I don't need to learn to deal with this problem, or should I learn how best to handle this situation?
